Drystone provides a convenient sanity check that the CPU is running at full
speed. Add this as a command which can be enabled as needed.

Note: I investigated using Coremark for this but there was a license
agreement and I could not work out if it was GPL-compatible.

Instead of selecting REGEX when NET is enabled, make it the default, but
allow boards that are tiny to disable it and lose functionality on all
but the first Ethernet adapter.

cm-bf548, bf538f-ezkit, and bf533-stamp need this. None appear to have
more than one Ethernet interface.

Commit 9ba9e85f (net: Fix NET_RANDOM_ETHADDR dependencies)
accidentally dropped CONFIG_LIB_RAND defines for 14 Blackfin boards.

Prior to that commit, those boards defined CONFIG_LIB_RAND, but not
CONFIG_NET_RANDOM_ETHADDR.  So, commit 9ba9e85f should not have
touched them, but in fact it ripped CONFIG_LIB_RAND off from all the
header files, which caused undefined reference to srand and rand.
CONFIG_LIB_RAND=y must be revived for such boards.

BTW, this commit indeed makes it better, but even with this fix,
three boards (bf533-stamp, bf538f-ezkit, cm-bf548) still can not
build due to region 'ram' overflowed error.  This was cause by
commit 6eed3786 (net: Move the CMD_NET config to defconfigs)
because CMD_NET selects NET, and NET selects REGEX.  Eventually,
some boards were newly enabled with CONFIG_REGEX, increasing the
memory footprint.  A patch is expected to fix the build error.

NET_RANDOM_ETHADDR depends on lib/rand.c. This patch adds dependency to
Kconfig to ensure that library is also compiled.

Remove the definitions from Blackfin boards' include/configs.

Kconfig option added for devices which support RSA Verification.
1. RSA_SOFTWARE_EXP
Enables driver for supporting RSA Modular Exponentiation in Software
2. RSA_FREESCALE_EXP
Enables driver for supporting RSA Modular Exponentiation using Freescale specific
driver

The above drivers use RSA uclass

For FIT signature based approach to work, RSA library needs to be selected.
The FIT_SIGNATURE option in Kconfig is modified to automatically select RSA.
Selecting RSA compiles the RSA library required for image verification.

The private libgcc is supported only on ARM, MIPS, PowerPC, SH, x86.
Those architectures should "select" HAVE_PRIVATE_LIBGCC and
CONFIG_USE_PRIVATE_LIBGCC should depend on it.

Currently, this option is enabled on Tegra boards and x86 architecture.
Move the definition from header files to Kconfig.

CONFIG_SYS_HZ is always defined as 1000 in config_fallbacks.h
(but some boards still have redundant definitions).

This commit moves the definition and the document in README to
Kconfig.  Since lib/Kconfig can assure that CONFIG_SYS_HZ is 1000,
the sanity check in lib/time.c should be removed.
